Google Search Engine Optimization: Google isn’t just splitting its search indexes into desktop and mobile versions… it could start prioritizing mobile, too. The internet firm has started experimenting with a “mobile-first” index that primarily ranks sites based on their phone-friendly pages. The company will take the months ahead to refine the experience and make sure that computer users aren’t left by the wayside, but your PC will no longer be the absolute center of Google’s search universe.

Google Search Engine Optimization, Mobile SEO Optimization

Having recently said that it will show different search results to mobile and desktop users, Google now has another search related announcement. Reacting to the fact that most searches are conducted from mobile devices, search results will be ranked according to sites’ mobile content.

Google says that it has “begun experiments to make [its] index mobile-first”, and it’s a move that essentially says that mobile searchers are more important than the rest. In light of the recent splitting of mobile and desktop indexing, the announcement is hardly a bolt out of the blue, but it’s still something that many site owners will need to take action about.

While the change has just been announced, Google says that it will be gradually introduced over the coming months. Ranking algorithms will ultimately look to the mobile index to determine how results should be ordered, Google says desktop users are not going to be abandoned.

Although our search index will continue to be a single index of websites and apps, our algorithms will eventually primarily use the mobile version of a site’s content to rank pages from that site, to understand structured data, and to show snippets from those pages in our results. Of course, while our index will be built from mobile documents, we’re going to continue to build a great search experience for all users, whether they come from mobile or desktop devices.

We understand this is an important shift in our indexing and it’s one we take seriously. We’ll continue to carefully experiment over the coming months on a small scale and we’ll ramp up this change when we’re confident that we have a great user experience.
